I got to play it today at the Xbox One Truck in Toronto.
The new controller, well, mainly the the new triggers are awesome. Being able to feel that response when the tires are slipping as you accelerate too hard, or being able to feel the ABS brakes grabbing when you brake too much is fully awesome.
The demo they have on the trucks is for Laguna Seca.
You have 5 options for the cars - The Audi R18, Ferrari F12, Fiesta ST (might be the Focus actually), Mclaren MP4-12C and the Mercedes Benz 300 Gullwing.
I did 2 races, one with the ST and one with the Mclaren. Assists set to Hard.
Well, it looked great - and it was still Forza. I'm not sure what they could do to make it different though - I'm worried I might get burned out on it.
One major thing which I'm sure we've already noticed, but I noticed first hand - Reflections on the god damn windscreens.
